Abstract

The closure of a large hiatal hernia still represents a challenge for the surgeon. Mesh reinforcement of a hiatoplasty generally decreases recurrence rate. An artificial mesh is cheaper compared with a biologic one, but has a higher complication rate. Our aim was to introduce a new biologic reinforcement method with less expenses. During organ donation for transplantation, tissue islets from pericardium and fascia lata were cryopreserved in a tissue bank. Later, the grafts were transplanted on the diaphragm of mongrel dogs. After 1, 3, and 6 months, the animals were sacrificed, and the transplanted patches were macroscopically and microscopically examined. There were no macroscopic signs of inflammation, abcedation, or significant adhesion formation. The grafts were well recognizable, with palpable thickening and moderate shrinkage. Microscopically, an organization process with fibrosis, neovascularization, and peritoneal integration could be observed. Reinforcement of a hiatoplasty with connective tissue transfer either with cryopreserved or autologous tissue is a good option. This is a cheap and easy method, which should also be tested in human interventions.
